Digital workers at Al Jazeera America were moved to join a union in search of "coherence, structure and clarity" in resolving a disparate set of grievances.

"In talking about this with people in different departments, we realized that there were many very different issues of concern to people," Gregg Levine, the digital news editor of Al Jazeera America, said Thursday after formal disclosure of the move.

The digital workers joined editorial counterparts at several other media organizations that have recently opted to go union.
